I'm no expert on this I own one asymmetric ball but I've found that the asymmetric balls seem to compound whatever I do with it. If I'm up the back of the ball with either type they tend to roll longer and break harder farther down lane, if I'm more around the side of the ball they tend to break earlier with more of an sweep motion. This reaction is the same between both types of balls but I do believe it is much more pronounced with the asymmetric balls I also believe That my asymmetric ball tend to hit much better when I'm up the back of it.
On your Bonus question the Thug Unruly actually has a 500/2000 factory finish on it not just 2000. 30 seconds at 500 then 10-15 seconds at 2000 on a ball spinner. I'm not a big fan of resurfacing balls by hand if you need to refresh one between resurfaces or adjust your surface to fit the shot that night hand adjustments are great but it is no where near the same thing as finishing on a ball spinner.
